摘要: We report linear and non-linear optical properties of a new quaternary chalcogenide glass series Ge19-ySe63.8Sb17.2Tey (y = 0, 2, 4, 6, 8, 10). In properties; refractive index, extinction coefficient the Tauc gap are reported their variation with Te content has been discussed. third order nonlinear susceptibility index The also normalized photon energy. A correlation between Results indicate that these materials may find applications in modern devices.
